Ansell steel fixers drift set Product information Specially engineered Drift based on feedback from Steel Fixers. It is used to line up holes in girders and cross members. The unique tapered design means that drift can be used for several hole sizes. As a result the steel fixers drift is more practical and a lot more cost effective with a 'one drift fits all' approach. Size 1 10-19mm (just over 3/8" to just under 13/16") Size 2 14-22mm (9/16" to 7/8") Size 3 18-25mm (3/4" to 1") A hole is provided to accommodate a tool safety lanyard. The flats on the heads of the drifts enable an adjustable podger spanner to be used to release the drift (if required).
